Abstract
A respiratory system comprises a breathing gas source which is connected to a feed part such as a tracheal tube connection to a closed circuit respiratory gas ventilation circuit. The gas ventilation circuit has a pressure relief connection therein. The gas feed part is connected to the breathing gas source and to the breathing gas supply through a control which controls the feed of a pulse of gas through at least one gas nozzle which is mounted to extend into the feed part at a location to form a suction area in the feed part which induces the flow of the ventilating gas through the feed part and the closed circuit respiratory gas ventilation circuit.
